The auxiliary group approach developed in Paper 1 [R. Dirl, P. Kasperkovitz, M. I. Aroyo, J. N. Kotzev, and M. Angelova-Tjurkedjieva, J. Math. Phys. 27, 37 (1986)] is generalized for the case of corepresentations of antiunitary groups. It allows us to reduce the multiplicity problem and to derive consistent generating relations for the elements of the reducing matrices for coreps. Two examples are worked out to illustrate the general scheme.
